Describe the angle relationship and solve for the x.

​

Answers

Answer:

x = 25

Step-by-step explanation:

The shown angles appear to be on a straight line

Angles on a straight line have a sum of 180°

That being said we can create an equation using this relationship

180 = x + 2 + 153

now we solve for x using basic algebra

step 1 combine like terms

153 + 2 = 155

now we have 180 = x + 155

step 2 subtract 155 from each side

180 - 155 = 25

155 - 155 cancels out

we're left with x = 25

a wildlife manager determines that the function y=200x1.07* represents the deer population at a state park x years after the population is first counted. what is the population after 12 years? what is the initial population? what is the percentage rate? complete the table below.

Answers

Answer:

Table:

0,200

4, 262

8,344

12, 450

Population after 12 years is 450 deer

Initial population is 200 deer.

Step-by-step explanation:

You take the x in the table and plug it in as an exponent so you will need a calculator or multiple the 1.07 by that many times so 1.07 12 times multipled by itself. and the initial is 0 years so anything to the exponent of 0 is 1 so that show i got 200 for the x=0

Answer:

y= 34

Step-by-step explanation:

Plug in 9 for X and solve

choose yes or no to tell if the fraction 2/9 will make each equation true
81 x =18
900 x = 200
72 x =16
450x = 100

Answers

Answer:

yes

Step-by-step explanation:

to see if 2/9 will make each equation true, you replace 'x' with 2/9, so let us do just that-

81*2/9=18

900*2/9=200

72*2/9=16

72*2/9=16

450*2/9=100

now, seeing as how every answer we've gotten matches the answers of the algebraic equations, the answer is yes 2/9 does make each equation true

good luck :)
